-Furufuru future [recently released as DLC]-Mahou wo Kakete [recently released as DLC]-Kimi wa Melody [still not DLC yet, was in Shiny Festa]-Brand New Day [DLC]-Watashi wa Idol [latest DLC]-Do-Dai [Standard in imas2]-MEGARE! [standard]-Town [idk what to classify this as]-My Song [Standard]-Flower Girl [has never been in any game]-Little Match Girl [DLC/standard]-relations [standard]-arcadia [same as flower girl]-Agent [DLC]-Go my way [standard]

seeing a pattern? The vast majority of the songs were either included in the game or recently released as DLC right after the concert. Maybe that's a way to predict what songs will be future DLC? I dunno, it's interesting either way.

idk it probably doesn't mean anything but I would be willing to bet on Kimi wa Melody as DLC...
